These pictures are fantastic, and I couldn't agree more about the museo antropología. I've been there three times and I'd love to go back. There were two things in particular that blew my mind the first time I visited:

There's an exhibit about the ancient city of Tenochtitlan, how it was built on top of a lake, the wild history of things that happened there, etc. It was only when I was almost done with the exhibit I realized [edit] Tenochtitlan is Mexico City, the place I had been for the past few days. It was hard to reconcile.

My main takeaway about the Aztecs from history class was that they were the victims of the Spanish conquistadores. That's true, but they have a fascinating backstory where they were the conquerors of other groups and did a variety of amazing and terrible things. I had a one-dimensional view of the region, and I had never even heard of some of the people that they had conquered.
